Abstract (en)
The invention describes a total isolation diverter valve comprising a valve body whereon a main inlet conduit for inletting a fluid, a first outlet conduit for outletting the fluid and at least one second outlet conduit for outletting the fluid are obtained. The first outlet conduit for outletting the fluid is provided with a first fluid adhesion inner surface and the second fluid outlet conduit is provided with a second fluid adhesion inner surface. Between the main fluid inlet conduit and the two fluid outlet conduits a connection channel is interposed. On the connection channel at least one device for perturbing at least one of the first fluid adhesion inner surface and the second fluid adhesion inner surface is provided. The perturbation device is configured so as to cause a deviation of the fluid flow from the first fluid outlet conduit to the second fluid outlet conduit or vice-versa by exploiting a physical effect called Coand effect. The perturbation device comprises at least one perturbation orifice, which faces the first fluid adhesion inner surface, and at least one opening/closing element, configured for opening and sealingly closing a respective perturbation orifice.
